Sibling Maltreatment: The Forgotten Abuse

Great advances have been made in the study of family violence in the past 30 years. However, sibling abuse and its prevalence in the family have largely been overlooked. In this article, the major issues associated with sibling maltreatment are highlighted, and strategies for helping the victims and perpetrators of sibling abuse and their families are described.     

The roles of delay and retroactive interference in retrieval-induced forgetting

When subjects study items from different categories and then repeatedly retrieve some of the items from some of the categories, retrieval practice typically improves recall of the practiced items but impairs recall of related but unpracticed items, relative to control items from unpracticed categories. Here, we report the results of three experiments, in which we examined practiced and unpracticed items’ delay-induced forgetting (Exp. 1) and their susceptibility to retroactive interference (Exps. 2 and 3). Control items showed the expected memory impairment after longer delay between practice and test and in the presence of retroactive interference. In contrast, both the practiced and the related unpracticed items showed hardly any forgetting under these conditions. The findings are consistent with the results from recent testing-effect studies, which have reported reduced delay-induced forgetting and reduced susceptibility to interference for retrieval-practiced items, and generalize the results to related unpracticed items. The findings are discussed with respect to the inhibitory and noninhibitory accounts of retrieval-induced forgetting, as well as the possible role of selective segregation processes, which may be induced by retrieval practice.     

Why are women more religious than men? Testing the explanatory power of personality theory among undergraduate students in Wales

This study tests the explanatory power of personality-based psychologically grounded theories to account for the well-established finding within the psychology of religion that within Christian and post-Christian contexts women are more religious than men. A sample of 1682 undergraduate students in Wales completed the short form of the Eysenck Personality Questionnaire Revised together with the adult form of the Francis Scale of Attitude towards Christianity and measures of frequency of church attendance, and frequency of personal prayer. These data confirm that women record higher levels of religiosity and lower levels of psychoticism, and demonstrate that psychoticism is the strongest predictor of individual differences in religiosity. Multiple-regression analyses show that, when individual differences in personality are taken into account, biological sex adds no further impact on religiosity. This finding suggests that higher levels of religiosity among women may be interpreted as a function of basic psychological differences in levels of psychoticism rather than as a sociological function of being female.     

Retrieval practice can eliminate list method directed forgetting

It has recently been shown that retrieval practice can reduce memories’ susceptibility to interference, like retroactive and proactive interference. In this study, we therefore examined whether retrieval practice can also reduce list method directed forgetting, a form of intentional forgetting that presupposes interference. In each of two experiments, subjects successively studied two lists of items. After studying each single list, subjects restudied the list items to enhance learning, or they were asked to recall the items. Following restudy or retrieval practice of list 1 items, subjects were cued to either forget the list or remember it for an upcoming final test. Experiment 1 employed a free-recall and Experiment 1 a cued-recall procedure on the final memory test. In both experiments, directed forgetting was present in the restudy condition but was absent in the retrieval-practice condition, indicating that retrieval practice can reduce or even eliminate this form of forgetting. The results are consistent with the view that retrieval practice enhances list segregation processes. Such processes may reduce interference between lists and thus reduce directed forgetting.     

Training Public School Special Educators to Implement Two Functional Analysis Models

The purpose of this study was to investigate the efficacy and efficiency of a training package to teach public school special educators to conduct functional analyses of challenging behavior. Six public school educators were divided into two cohorts of three and were taught two models of functional analysis of challenging behavior: traditional and trial-based functional analysis. The effect of the training package on functional analysis implementation was evaluated using multiple-baseline designs across participants for each functional analysis model. The sequence of functional analysis models taught was counterbalanced across cohorts. Following the training package, all participants reached 100 % implementation fidelity during role-plays and classroom sessions with students, and maintained high fidelity at follow-up role-play sessions. Data on training duration, trials to criterion, and social validity revealed that trial-based functional analysis training had a shorter duration and was rated as the more favorable functional analysis model.
